Does the work you do on a book when you lift it onto a shelf depend on the path taken?
No, the work done to lift a book onto a shelf does not depend on the path taken. The work done is determined by the height the book is lifted to and the force needed to lift it against gravity, not the specific path taken.
Is work done if you lift a brick?
Yes, work is done when you lift a brick against gravity because you are exerting a force over a distance in the direction of the force of gravity. Work is defined as force multiplied by distance in the direction of the force, so lifting the brick requires work to be done.
Is work being done when you lift a box?
Yes, work is being done when you lift a box against the force of gravity. Work is defined as the force applied over a distance, and in this case, the force you exert to lift the box is acting over a vertical distance, thus work is being done.
Which correctly describes why work is done when you lift a book?
Work is done when you lift a book because you are applying a force over a distance in the direction of the force. This transfers energy to the book, giving it gravitational potential energy. Work is calculated as the force applied multiplied by the distance the object is lifted.
Explain why you are doing work on a book when you pick it up but not when you carry it across the room.?
When you pick up a book, you are exerting force to lift it against gravity, which requires work to be done. However, when you are carrying the book across the room at a constant height, there is no change in the book's potential energy, so no work is being done in that direction. Work is done when there is a force applied over a distance in the direction of the force.
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
Is t true the kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no
True or false the kinetic energy of a book shelf is equal to the work done to lift the book to the shelf?
false

What is the relationship between the work done to lift a book to place it on a bookshelf and the potential energy of the book on the shelf?
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
What describes why work is done when you lift A book?
Work is being done when you lift an object because you are applying a force (lifting) parallel to and against another force (gravity). If you carry an object, you are still applying a force directed upwards, however your motion is perpendicular to gravity (as you walk to the east, for example). In this case, NO work is done, regardless of how far or how long you walk/carry. When you set the object down, again, your force is parallel to and with gravity. Therefore, work is done, however, in this case, it'll be negative.
How much work is done to lift 40kg of bricks to a height of 10m?
The work done to lift 40kg of bricks to a height of 10m can be calculated using the formula: Work = Force x Distance. The force required to lift the bricks is equal to the weight, which is mass x gravity (40kg x 9.8m/s^2). Plug these values into the formula to find the work done.
